网络中利用APC的Network Information Server实现多台主机自动关机(接在同一个UPS上)
下文只是个简单的例子,欢迎指正.
作者:congli
日期:2005.9.14
实验环境:
APC UPS 1000W
主机A IP:10.0.0.200 COM1接UPS
主机B IP:10.0.0.202 (运行在VM中)
PS:主机A及主机B均由UPS供电.
主机A:
1.安装apcupsd
# cd /usr/ports/sysutils/apcupsd
# make install clean
代码:
[ ] CLIENT_ONLY Build apcupsd client only (no network server)
[X] CGI Compile with CGI programms to show status
[ ] USB Compile with USB Support (READ MANUAL!!!)
[X] SNMP Compile with SNMP Support (READ MANUAL!!!
2.设置apcupsd
# cd /usr/local/etc/rc.d
# mv apcupsd.sh.sample apcupsd.sh
# vi /etc/rc.conf
代码:
apcupsd_enable="YES"
3.设置配置文件
# cd /usr/local/etc/apcupsd
# vi apcupsd.conf
代码:
DEVICE /dev/cuaa0 # COM1
NISIP 10.0.0.200 # NISIP
BATTERYLEVEL 5 # 电量百分比,到达此数值,计算机自动关闭
4.启动apcupsd
# /usr/local/etc/rc.d/apcupsd.sh start
5.测试
# apcaccess

如果apcupsd启动后马上运行apcaccess,可能会出现如下错误,应该是主机与UPS通信未完成的关系,多等一会就好了.
代码:
FATAL ERROR in apcaccess.c at line 243
tcp_open: cannot connect to server 10.0.0.200 on port 3551.
ERR=Connection refused
主机B:
1.安装apcupsd
# cd /usr/ports/sysutils/apcupsd
# make install clean
代码:
[X] CLIENT_ONLY Build apcupsd client only (no network server)
[ ] CGI Compile with CGI programms to show status
[ ] USB Compile with USB Support (READ MANUAL!!!)
[ ] SNMP Compile with SNMP Support (READ MANUAL!!!
2.设置apcupsd
# cd /usr/local/etc/rc.d
# mv apcupsd.sh.sample apcupsd.sh
# vi /etc/rc.conf
代码:
apcupsd_enable="YES"
3.设置配置文件
# cd /usr/local/etc/apcupsd
# vi apcupsd.conf
代码:
UPSCABLE ether
UPSTYPE net
DEVICE 10.0.0.200:3551
NETSERVER off
NISIP 10.0.0.200 # NISIP
4.启动apcupsd
# /usr/local/etc/rc.d/apcupsd.sh start
测试:
关闭UPS外部电源,并过几秒后重新打开UPS外部电源,主机A及主机B均显示信息,当UPS电量低致BATTERYLEVEL指定值,主机A,B及UPS会自动关闭.
主机A:
代码:
